A Music Game to Play With Friends, on Real Instruments

Looking for a music game to play with friends? In ChordRunner you all play real instruments: open a room, share the code, and every chord appears for everyone at once. Play it on a piano, a MIDI keyboard or a guitar, from any browser.

No account, no download. The demo has limited content. Advanced features are in ChordRunner Premium.

  • MIDI keyboard
  • Digital or acoustic piano
  • Guitar
  • Computer, phone or tablet

What you need

  • A browser on a computer, tablet or phone (Chrome or Edge).
  • An instrument: USB MIDI keyboard, or a piano or guitar near the microphone.
  • Friends with the 4-digit room code.

A game night with real music

It is not a quiz about songs: you play the chords yourselves. Each right chord keeps your runner going, the leaderboard updates live, and at the end you see who was fastest and most accurate.

Mixed levels, same room

Friends who play at different levels still have fun together: chords stay readable as symbols, any voicing counts, and a beginner on guitar can share the room with a keyboard player.

Every week, a community event

Besides private rooms there is a weekly community event, where players around the world work towards a shared target.

Ideas for a game night

  • Warm-up round: major and minor chords only, so everyone starts on equal terms.
  • Swap instruments: the guitarist plays keys and the pianist plays guitar for one round.
  • Handicap round: the strongest player uses only seventh chords.
  • Final: the two best players face off while the others watch the leaderboard.

Before your first match

  1. Use Chrome or Edge on a computer, tablet or phone.
  2. Plug in a USB MIDI keyboard (detected automatically) or allow the microphone for a piano or guitar.
  3. Pick the chord level for the room: from major and minor triads up to 13th chords.
  4. Any voicing counts: root position, inversions or open shapes.
